| FastEBM - High Productivity Electron Beam Melting Additive Manufacturing Development for the Part Production Systems Market Electron beam melting additive manufacturing is used to
produce successive layers of a part in a powder bed and
offers the ability to produce components closest to their
final dimensions, with good surface finish. At this time the
process is faster than any other technique of comparable
quality, however the parts are not produced at sufficient
rate to make them economically viable for any but very high
value specific applications.
One key output of the project will be the knowledge
surrounding the use of the high powder electron beam gun,
including the process control, and modeled and validated
understanding of beam-powder bed interaction.
The target objectives is the transfer of the 2D model to a
3D model and its parallel implementation. The outcome of the
simulation will be compared with real experimental data and
therefore
the model parameters are adjusted in such a way that the
resulting numerical melt pool sizes correspond to the
experimental ones.
